. i FASTENING DEVICE FOR CHAIR-SEATS.

Specification of Letters Patent.

Patented Jan. 26, 1915.

Application filed January 22, 1914. Serial No. 813,747.

To all whom it may concern:

Be it known that I, JOHN W. HENRY, a citizen of the United States, residing at New York, in the county of New York and State of New York, have invented certain new and useful Improvements in Fastening Devices for Chair-Seats; and I do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to improvements in fastening devices for chair seats.

One object of the invention is to provide a fastening device for chair seats having an improved means for securing the inner end thereof in engagement with the bottom of the chair seat and means for rigidly fastening the outer ends to the under side of the seat frame.

Another object is to provide a fastening device of this character which will be strong, durable and inexpensive in construction, eflicient and reliable in operation and which may be readily applied to any chair seat having a solid base or bottom to firmly secure the seat to the seat frame of the chair.

WVith these and other objects in view the invention consists of certain novel features of construction, and the combination and arrangement of parts as will be more fully described and claimed.

In the accompanying drawings; Figure 1 is a bottom plan View of a chair seat frame showing the application of my improved fastening device for securing the seat to the frame; Fig. 2 is an enlarged detail sectional view on the line 2-2 of Fig. 1; Fig. 3 is a detail perspective view of one of the fastening devices; Fig. 4: is a detail sectional view on the line 44 of Fig. 1.

My improved chair seat fastening device is formed from a single strip of spring metal bent midway between its ends to form a seat engaging tongue 1 in the sides of which are formed notches or recesses 2 the purpose of which will be hereinafter described. The ends of the strip after forming the tongue 1 curve outwardly or diverge and on the extremities of the ends are right angularly formed frame engaging members 3, said members being bent to form shoulders 4 and lugs 5 which are adapted to respectively engage the inner edges and lower sides of the seat frame 6 of the chair. On the outer ends of the lugs 3 are formed right angularly disposed spurs or barbs 7 which are adapted to be forced into the under sides of the seat frame and which together with the shoulders 4: hold the attaching devices into firm engagement with the seat frame and against movement in any direction.

In order to engage the fastening device with the chair seat the latter are provided with depending staples or loops 8 which are secured in any suitable manner to the solid bottom of the seat near each corner thereof as shown. In fastening the seat to the chair frame the tongues 1 of the fastening devices are inserted through the staples or loops 8 a sufficient distance to permit the recesses or notches 2 in the sides of the tongue to spring into engagement with the sides of the staple, thus securely locking the fastening devices to the bottom of the seat. After thus securing the fastening devices the outer ends thereof are adjusted to bring the shoulders 4 thereon into engagement with the inner edges of the chair seat frame after which the spurs or barbs 7 are forced or driven into the lower sides of the seat frame 6 thus securing the outer ends of the fastening devices to the seat frame. When thus arranged and secured the fastening devices will hold the seat in firm engagement with the seat frame and will prevent the seat from slipping in any direction.

My improved fastening devices are formed of any suitable metal and the strips of metal from which they are constructed may be round, square, flat or any suitable shape and by constructing the same as herein shown and described it will be seen that they are secured to the seat frame for holding the seat in position thereon without the use of separate fastening devices.

From the foregoing description taken in connection with the accompanying drawings, the construction and operation of the invention will be readily understood without requiring a more extended explanation.

Various changes in the form, proportion and the minor details of construction may be resorted to without departing from the principle or sacrificing any of the advantages of the invention as claimed.

Having thus described my invention, what I claim is;

1. A fastening device for chair seats co1nprising a loop adapted to be secured to the lower side of the chair seat, a spring metal tongue adapted to be engaged with said loop and having in its side notches adapted to spring into engagementwith the sides of the loop, whereby said tongue is looked into engagement therewith, and means to secure the ends of said fastening device to the chair seat frame.

2. A fastening device for chair seats comprising a loop adapted to be secured to the lower side of the chair seat, a spring metal tongue adapted to be engaged with said loop and having in its sides notches adapted to spring into engagement with the sides of the loop, whereby said tongue is locked into engagement therewith, fastening devices on the outer ends of said tongue, said fastening devices comprising frame engaging members having shoulders adapted to engage the inner edge of the seat frame, lugs adapted to engage the lower side of the seat frame, and spurs on the ends of said lugs adapted to be forced into the lower side of the seat frame, whereby the fastening device is rigidly secured to the frame in position to hold the seat into engagement therewith.

3. A seat fastening device formed from a single strip of spring metal bent inter mediately its ends to form a tongue, said tongue having in its sides notches, said sides of the tongue being curved outwardly and having on their outer ends frame engaging members comprising shoulders adapted to be engaged with the inner edges of the seat frame, lugs adaptedto engage the under side of the seat frame, and spurs on the outer my hand in presence of two subscribing witnesses. r
